Keystone    Gearless  Hay   Loader 


The  Keystone  Gearless  Hay  Loader 


Keystone  gearless  hay  loader 


The  Keystone  gearless  hay  loader  is  of  the  rake  type,  and  will  load  either  from  the  swath  or 
light  windrow.  One  man  can  drive  the  team  for  a  few  minutes  until  a  good  quantity  of  hay  has 
collected  on  the  rear  end  of  the  wagon.  He  can  then  stop  the  team  and  distribute  the  hay  evenly 
on  the  rack.  By  repeating  this  operation  a  good  size  load  may  be  gathered  in  fifteen  or  twenty 
minutes.  The  entire  absence  of  gears,  sprockets,  chains,  etc.,  make  this  a  remarkably  simple  and 
light  draft  loader.     The  absence  of  complicated  working  parts  also  increases  its  durability. 


Wheels 

The  Keystone  has  not  the  swinging  motion  common  to  other  loaders,  but  runs  steadily  without 
twisting  or  straining.  This  valuable  feature  is  secured  by  reducing  the  length  of  the  axle  and 
placing  the  wheels  well  under  the  loader.  This  construction  also  permits  the  driver  to  drive 
closer  to  fences  and  ditches  than  would  be  possible  if  the  wheels  were  sel  at  an  ordinary  distance 
from  the  loader.  The  wheels  are  strongly  constructed  of  steel  with  wide,  well  lugged  tires  which 
secure  sufficient  draft  to  operate  the  loader  under  all  conditions.  The  axle  is  of  solid  steel,  strong 
enough  to  stand  all  strains.

Note  the  roller  and  bracket    connection    between    rake 
arm  and  rake  bar,  and  the  peculiar  shape  of  rake 
arm.    Also  note  manner  in  which  teeth  are 
fastened  to  the  rake  bar 


Main  Frame 

The  frame  is  strongly  constructed.  An  angle  steel 
rear  cross  brace  makes  the  loader  rigid  and  prevents 
swinging  or  swaying  in  rough  places. 

Drop  Gate 

The  drop  gate  has  a  wide  range  of  adjustment  and 
can  be  easily  raised  or  lowered  to  suit  the  operator. 

Steel  Rake  Arms 

Oil  tempered  steel  rake  arms  are  used  for  connect- 
ing the  rake  bars  to  the  rock  shafts.  The  ends  of  these 
rake  arms,  which  are  attached  to  the  rake  liars  by 
means  of  brackets,  are  provided  with  rollers  to  permit 
the  bearings  to  move  more  easily  and  to  eliminate  fric- 
tion. These  rake  arms  are  of  a  peculiar  curved  shape 
and  permit  the  rake  heads  to  spring  up  when  passing 
over  obstructions,  in  this  way  lessening  the  danger  of 
breakage. 


Flexible  Rake  Heads 

The  rake  heads  have  a  great  deal  of  flexibility  and 
will  bend  forward  and  backward  or  tilt  to  either  side. 
This  allows  them  to  pass  over  rough  places  or  obstruc- 
tions in  the  field  without  becoming  bent  or  broken. 
The  teeth  are  of  the  triple  coil  type,  made  of  oil  tem- 
pered steel,  and  are  held  in  good,  solid  castings.  The 
rake  arms  are  of  strong  steel  and  have  sufficient  flexibil- 
ity to  prevent  the  rake  heads  from  digging  into  the 
ground  and  raking  trash  with  the  hay.  Another  ad- 
vantage is  that  the  rake  heads  act  independently  of  each 
other  and  when  one  is  passing  over  an  obstruction  the 
work  of  the  others  is  not  interfered  with.

Adjustable  Ground  Wheels 

The  ground  wheels  on  the  Keystone  gearless  loader  can 
be  adjusted  to  different  heights  without  the  use  of  any  clumsy 
or  inconvenient  raising  or  lowering  device.  These  wheels 
are  equipped  with  roller  bearings.  The  weight  thrown  upon 
them  is  just  enough  to  keep  the  loader  well  balanced. 


Hitching  Device 


The  driver  who  is  using  the  Keystone  never  needs  to  get  down  off 
the  load  to  disconnect  it  from  the  wagon.  A  simple,  reliable  hitching 
device  is  provided  which  is  operated  by  a  rope  that  extends  from  the 
release  lock  to  the  top  of  the  load.  Pulling  this  rope  disconnects  the 
loader  from  the  wagon  and  leaves  it  standing  in  the  field  in  an  upright 
position  ready  for  the  next  wagon.  When  hitching  the  loader  to  the 
wagon  it  is  not  necessary  to  back  the  center  of  the  wagon  exactly  up  to 
the  hitching  device.  The  release  lock  is  mounted  on  a  rod  several  feet 
long,  and  when  unlatched  this  rod  slides  through  a  sleeve  mounted  on  a 
small  turntable.  This  permits  the  release  lock  to  be  pulled  out  and  turned 
in  any  desired  direction,  then  when  the  wagon  is  backed  up  the  device 
latches  automatically,  holding  the  loader  in  the  proper  position.

The  above  cuts  show  the  hitching  device  used  on  the  Keystone  gearless  hay  loader.     In  Fig.  1  the  device  is  latched  as  it  is  when  the 

loader  is  in  operation.     In  Fig.  2  the  rod  has  been  pulled  out  its  full  length  and  swung  around  to  the  left  in  order  to  hitch 

to  a  wagon.     The  rod  can  be  swung  all  the  way  around  to  the  right  or  left

The  illustrations  above  show  the  pitmans  and  fulcrum  levers  which  operate  the  rake  bars  and  rock  shafts  in  two  different  positions 


Operating  Mechanism 


The  Keystone  gearless  loader  is  equipped  with  two  square  rock  shafts,  which  are  a  great 
improvement  over  the  crooked  crank  shafts  used  on  other  loaders  of  this  type.  These  rock  shafts 
are  timed  to  raise  and  lower  the  rake  heads  at  the  proper  time  and  in  the  proper  way  to  gather 
all  the  hay  without  digging  into  the  ground.  The  strokes  of  the  rake  heads,  because  of  the  design 
of  the  rock  shafts,  are  long  and  elliptical.  The  rake  heads  on  the  Keystone  move  parallel  to  the 
ground  during  nearly  one-half  the  stroke.  On  other  rake  loaders  the  strokes  are  short  and  choppy, 
requiring  a  high-speed  operating  mechanism.  The  short,  choppy  strokes  also  dig  up  the  ground 
and  thresh  the  leaves  and  heads  off  the  hay.  When  a  crooked  crank  shaft  is  used  it  is  very  hard 
to  keep  the  rake  heads  working  in  time  but,  with  the  rock  shafts  which  are  used  on  the  Keystone 
gearless,  this  trouble  is  eliminated. 

Another  good  feature  of  the  Keystone  is  that  on  the  return  stroke  the  rakes  are  raised  high 
from  the  ground  so  that  they  do  not  push  the  hay  back  or  become  wrapped. 

On  this  loader  the  power  is  transmitted  from  the  main  wheel  by  means  of  cranks  securely 
keyed  to  the  axle  outside  of  the  wheel.  These  cranks  are  connected  by  means  of  pitmans  to 
powerful  fulcrum  levers,  which  in  turn  drive  the  rake  bars. 


Keystone  Gearless  Hay  Loader 


This  illustration  shows  how  each  set  of  the  rakes  moves  along  the  ground  during  a  large  part 
of  the  stroke,  and  that  the  strokes  are  so  timed  that  one  set  of  rakes  is  moving  along  the  ground 
practically  at  all  times.  This  means  that  all  the  hay  will  be  gathered  and  elevated  onto  the  wagon. 
It  also  means  that  it  is  not  necessary  to  operate  the  rake  bars  at  a  high  speed  and,  therefore,  the 
hay  is  handled  in  a  very  gentle  way  and  moves  slowly  but  surely  up  the  elevator.  The  leaves  and 
blossoms,  which  are  the  most  valuable  part  of  the  hay,  are  not  threshed  off.  If  the  strokes  of  the 
rakes  were  short  and  choppy,  it  would  be  necessary  to  operate  them  at  a  high  rate  of  speed.  This 
would  be  sure  to  thresh  the  leaves  and  blossoms  off  the  hay.
